# Remove contacts from a notification configuration

POST https://api.modulards.com/api/public/v1/alerts/{alert_id}/contacts/detach
Content-Type: application/json

Removes the contacts you list in `contacts` from a notification configuration. It is the counterpart of "Add contacts to a notification configuration" and answers the same way.

**Body**
- `contacts` (array of integers, required): ids of the contacts to remove, 1 to 50. Each must be an existing contact.

**Errors**
- **422**: `contacts` is missing, empty, has more than 50 ids or contains an id that is not a contact. The body is checked before the configuration, so a configuration of another organization answers 404 only when the body is valid.
